Quick connect anchor for poured concrete ceilings on metal or wood decks

Abstract

An internally threaded anchor for use in poured concrete floors having a metal deck or a wood form. The threaded anchor provides quick and easy attachment to threaded support rods that carry racks for utilities, piping, or ceiling grid systems. Each threaded anchor is capable of accepting different diameter rods or bolts with different thread cuts. Each anchor accepts the different diameter threaded rods by a single insertion motion, without the need to thread the rod into the anchor. Full insertion is visually verifiable when the marked end of the rod inserted into the anchor is no longer visible. An authentication tag visible upon full insertion indicates that authorized rod is being used.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of application Ser. No. 14 / 225,019 filed Mar. 25, 2014 for Quick Connect Threaded Anchor For Poured Concrete, Metal Deck And Wood Frame Floors.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to improvements in anchors for poured concrete, metal deck or wood deck ceilings in multi-story buildings, and more particularly, pertains to new and improved threaded anchors that are attached to the metal or wood deck prior to pouring of the concrete so that when the concrete sets, these anchors may be used as support points for suspended utilities such as plumbing pipes, mechanical piping, mechanical equipment, cable trays, bus ducts, HVAC ducts, electrical conduit, conduit racks, junction boxes and panels, or for seismic bracing for example.[0004]2. Description of Related Art[0005]Various concrete inserts or anchors have been used to retain support rods in pou...

AI Technical Summary

Benefits of technology

This patent is for an anchor used in construction. The anchor has multiple segment with internally threaded diameters that allow for attachment of different diameter threaded rods. The segments expand during insertion of the rods and move radially inward to engage the threaded rods. The rod has a visual indicator that indicates its placement in the concrete slab. The patient needs to look at the indicator on the rod to confirm full insertion and ensure maximum grasp between the anchor and threaded rod. This ensures that the rod is authentic and the correct number is being used. Overall, this design simplifies the installation process and ensures a secure connection between the anchor and rod.

Problems solved by technology

Because such anchors are utilized in high rise buildings in large quantity, threading a rod into each anchor is a very time consuming and inefficient procedure.

These concrete anchors do not provide a user with a visual indication of full engagement.

Even when the threaded rod or bolt cannot be turned any further in the anchor, full engagement is not assured.

Furthermore, these quick connect devices do not contemplate accepting more than one diameter of threaded rod.
